TURBlNE-MGTOH FOR BOlLER-TUBE CLEANERS, duo.

'To will m7111111, it may concern:

Be it known that I, HENRY F. WEINLAND, acitizen of the United States,residing at S iringfield, in the county of Clark and State ci Ohio, haveinvented certain new and useful Improvements in Turbine-Motors forBoiler-Tube Cleaners, &c., of which the following is a speciiication,reference being had therein to the accompanying drawings.

This invention relates to turbine-motors for boiler-tube cleaners, te.,and more particularly to turbine-motors intended `for use connectionwith water under pressure as a noter fluid, the motor being connectedwith a rotary cleaning-head, preferably provided withcentriiugally-acting cutter-bearing arms and traveling with said headthrough the tube to be cleaned. A structure of this type set forth inLetters Patent No. 730,994, granted June 1.6, 1903, to my Aassignee, TheLagonda Manufacturing Company. One of the requisites of a cleaner ofthis type is a speed of rotation suliciently high to cause thecentrifugally-acting cutterarmsrto accomplish their work, and oneof theelements on which this speed is dependent is the diameter of theturbinew'heel. These cleaners are made in different sizes to correspendto the different sizes of boiler-tubes to be cleaned, and while thelarger sizes of boiler-tubes are of a diameter such as to accommodate amotor comprising a wheel oi a diameter sul'licient to give the necessarypower and speed it has been found in practhat the smaller tubes will notadmit a motor having a wheel of a diameter suliiciently great to developthe necessary power andv speed ot rotation.

It the object oi my present invention to provide a turbine-motor for usein connection with boiler-tube cleaners of the class just referred towhich will develop greater power and speed in proportion to its diameterthan the motors heretofore used for this purpose, so that when myimproved motor is made oi a diameter suliciently small to enable it topass tlnough the smaller size of boiler-tubes suiiioi ent to cause thecutter-arms to do their wei-l: properly.

A further object of my present invention Specification of LettersPatent.

is to provide a construction such that the parts may be readilyassembled and taken apart, ample provision being made to reduce frictionand wear, and to provide a structure which is at the same time elicientand inexpensive.

Tothese ends my invention consists in certain novel features which Iwill now roceed to describe, and will then particular y point out in theclaims.

In the accompanying drawings, Figure 1 is a view of a turbine-motorembodying my invention in one form, the casing being shown inlongitudinal section and the internal structure in elevation. Fig. 2 isa View similar to Fig. 1, but with the internal structure also insection; and Fig. 3 is a transverse sectional view taken on the line ma: of Fig. 1 and lookinir in the direction ofthe arrows.

lIn the vaccom anying drawings I have shown a preferre embodiment of myinvention in which the structure comprises an outer casin 1, preferablyin the form of a cylindric tu e, which may be threaded at one end, asindicated'at 2, to provide for the attachment theretocf the hoseconnection by means of which water under pressure is supplied to themotor. Within this casinur are located two heads 8 and 4, separated Cbya distance sufficient to admit between them a turbine-wheel. in the formof blocks fitting within the casing and secured in position by screws 5or in any other suitable manner. Said blocks constitute at one/and thesame time bearings for the rotatory parts and guides for the waterjets'to direct the same properly against the water-wheels. These latter (twoin number) are indicated, respectively, by the numerals 6 and 7 and aremounted on a shaft S, the blocks 3 and 4 being centrally apertured forthe passage of said shaft.

The block 3 has a central aperture or bore 9 of considerably reaterdiameter than the portion of the sha t 8 which passes through saidblock, so as to form a space or chamber 1 0'. annular in form andadapted to receive antifriction balls or rollers placed between saidblock and the shaft to receive the radial thrust of the shaft-bearing-In the present instance I have shown a plurality of annular These headsare preferably TOO rows of haus 11 filling the chamber biok 3 sis@ hasan sndfihust 'hea-1 ,Cf ceive sn and thrust trsnsmtjbe 8 fom't' `e Workin a em'wmd i Y Y.

f't'o the wheel 6 so as to strike the vanes or buckets thereof at thedesired angle. 'The f passages 34 are preferably in the forni of groovesformed in the exterior of the block 3 and completed by the casing l,which forms their outer walls when the structure is assembled. The block4 lies between the wheels 6 and 7, and it is also provided `withwaterguiding passages 35,.which receive the water from the water-wheel 6and deliver it to the Iwater-wheel 7. These passages are preferablyformed in the same way as the Vpassages 34 by grooving or slotting theexternal surface of the block.

One of the distinguishing features of my present invention is that the'watenp'assages 35 of the second or forward blockare of considerablygreater cross-sectional area than the water-passages of the first orrear block. By practical experience and extensive tests I have foundthat when the two sets of waterpassages are thus proportioned a verymate-' rial gain in power and speed is made, whereas a motor otherwisesimilarly constructed, but

having the water-passages 35 of substantially the samev size as thewat-er-passages34, is inefficient and unsatisfactory.

Y tube being the size actually cleaned, Ivhave found that the'apparatuswith such a motor developedlsufiicient power and speed to clean thetubes in a perfectly satisfactory manner-l a result which, so far as Iam aware', has never been accomplished under similar conditions by acleaner driven bya motor` of the turbine type. i

In addition to fulfilling the essential re quirement of sufficient powerand speed with a small diameter the motor also has manifest advantagesin that the parts may be readily assembled or taken ap art whenrequired, that ample provision against excessive friction is made, andthatthe end thrust in each direction is properly supported. Anylooseness arising from wear'can be readily taken up by means of thescrew-plug l2. ItA will also be observed that the construction, whileefficient, is relatively simple and inexpensive.

It is obvious that various modifications in the details of constructionmay be made without departing from the principle of my inveiitio.i. Forinstance, either one of the bearing-blocks may be integral v,with thecasing, bef-ring-rolle'rs may be substituted for the bearing-balls, andthe type of water wheel and jet-guide employed may be of any I alsoprefer to so construct the water-passages 35 as tolgive bers, a rotatoryshaft mounted in said heads i and provided with water-wheels located infront of the respective heads, rolling antifric Vtion'elements locatedin the bearing-chambers betweenthe shaft and heads and arranged toreceive the radial thrust only, the rear head i being provided withl athrust-bearing for the rear. end of the shaft, the shaft being providedwitha collar in the rear of the front head, and the front head beingprovided with an abutment for said collar to receive the forward thrustof the shaft, substantially asidescribed.
